GENERAL INFORMATION
LK 816 ThermoKit E Eco is a loading group for heating applications
with solid fuel boilers and storage tanks. The loading group is in-
tended to ensure a high return temperature as well as an optimal
temperature stratification in the storage tank, thus increasing the
efficiency of the system. Tarring and condensation are prevented
which prolongs boiler life.
INSTALLATION AND MAINTENANCE
LK 816 ThermoKit E Eco is installed in the return circuit between the
solid fuel boiler and the storage tank. The group should be mounted
with the drive-shaft of the circulating pump in a horizontal position.
The tempera ture sensor is attached to the return circuit of the boiler.
The loading group is reversible and can easily be adapted for mounting
to the right or left of the boiler (See Figure 1 & 2 page 7).
For trouble-free operation of the heating application the piping
should not allow air pockets to be formed in the system. Should
this not be possible air vent valves have to be installed.
The loading group normally requires no maintenance. The instal-
lation should be checked regularly. Thanks to the three ball valves
any part can be changed without draining the system, should the
need for servicing arise.
DANGER!
Risk of electric shock!
•
Before starting installation work the power supply must be
reliably disconnected.
•
All work must be performed by qualified personnel.

THE FUNCTION OF THE LOADING UNIT DURING THE DIFFERENT
PHASES OF HEATING:
1. HEAT UP PHASE
The water circulates between boiler and loading group while the
temperature of the boiler is rising.
2. LOADING PHASE
The mixing valve starts to open and allows return water from the
storage tank to be mixed with supply water before it returns to the
boiler. The return temperature to the boiler is kept constant.
3. END PHASE
The mixing valve is fully open towards the storage tank. This results
in an optimal transfer of heat from the boiler and the storage tank
is filled with supply water. When the boiler has cooled the electronic
controller prevents re-circulation from storage tank to boiler.
4. SELF-CIRCULATION
In case of power failure or pump breakdown the electronic con-
troller can be manaully operated and the storage tank is loaded
through self-circulation.
